Hello! We use electrical for things related to electricity. E.g. Electrical generator --> a generator that produces electricity. Electric is used for devices or utilities that operates, or run on electricity. e.g. electric guitars, electric cars. Electronic is used for devices that are made up of many small parts, that manipulate the electric current internally, that are more 'technological' such as a computer, a smartphone etc. We can also use electronic for things that are traditionally physical. e.g. electronic book. I hope this is helpful!
